Polian began his coaching career in 1997 as a graduate assistant at Michigan State. In 1998, he was the tight ends and offensive line assistant at the University at Buffalo. In 1999 and 2000, Polian was a defensive graduate assistant at Baylor under Kevin Steele. Polian graduated from Baylor with a master's degree in 2000.[2]
Polian returned to Buffalo in 2001 as running backs coach and special teams coordinator, serving until 2003 all under coach Jim Hofher.[2] In 2004, he was assistant coach at the same positions at UCF under George O'Leary. From 2005 to 2009, Polian was special teams coordinator at Notre Dame under Charlie Weis. He also served as defensive backs coach in 2005, linebackers coach in 2006, and inside linebackers coach in 2007.[2] Notre Dame made three bowl appearances during Polian's tenure, including a win in the 2008 Hawaii Bowl.
He then was special teams coordinator and safeties coach at Stanford from 2010 to 2011 and was also recruiting coordinator in 2011.[2] Part of Jim Harbaugh's staff in 2010, Polian remained at Stanford under succeeding coach David Shaw. Stanford won the 2011 Orange Bowl after the 2010 season. In 2012, Polian was special teams coordinator and tight ends coach under Kevin Sumlin at Texas A&M, which won the 2013 Cotton Bowl Classic that season.[2]
Nevada
On January 11, 2013, the University of Nevada, Reno hired Polian as football head coach.[2] On November 27, 2016, Nevada parted ways with Polian,
effectively resulting in him being fired from Nevada based upon his poor performance.
On December 7, 2021, Polian was hired by LSU as the special teams coordinator, under Brian Kelly. In Feb 2023, Polian was demoted as Special Teams Coordinator and placed in a lesser, less challenging off field position after LSU special teams received a ranking of 130 out of 131 FBS teams. This after several high-profile miscues in critical games, attributed to Polian who, at times, appeared baffled as a Coordinator.
John Carroll
